Patented Jan. 3 1 939 UNITED STATES CONTAINER AND FLANGED CLOSURETHEREFOR Herman Carew, Easton, Pa., assignor to Dixie- Vortex Company,Easton, Pa., a corporation of Delaware Application July 25, 1936, SerialNo. 92,637

3 Claims. (Cl. 229-5.5)

' My invention relates to new and useful improvements in containers andflanged closures therefor and more particularly to a container andclosure formed of paper of the desired thickness and weight, theprincipal object of the invention residing in the formation of acontainer and closure in such a manner that a flanged closure may bereadily applied "to and held on the mouth portion of a container havinga tapered wall portion.

. Another object of the invention consists in reinforcing the containeraround themouth portion and providing by said reinforcement aperpendicular wall portion adapted to be frictionally l5 engaged by thedepending vertical flange of the closure.

A further object of the'invention resides in forming the closure ofrelatively thin material and turning a flange therefrom, a reinforcingring being positioned interiorly of and securedto the flange and adaptedto have frictional contact with the perpendicular wall portion of thecontainer.

A still further object of the invention consists in forming the closuresin a novel manner so that a plurality thereof may be stacked, they alsobeing so formed as to permit expansion as to diameter when applying andcontraction after application to permit snug engagement of the parts andsuch frictional engagement as will prevent accidental disengagement ofthe closure from the container.

With the above and other objects in view, which will appear as thedescription proceeds,

. my invention consists in the novel details of construction, andarrangement of parts, described'in the following specification andillustrated in the accompanying drawing, and while I have illustratedand described the preferred embodiments' of the invention, as they nowappear to me, it will be understood that such changes may be made aswill fall within the scope of the appended claims.

In thedrawing:--

Fig. 1 is aside elevation, with parts broken away, showing a closure inposition on a container.

Fig. 2 is a fragmental enlarged view showing a transverse verticalsection through a portion of the container and closure thereon.

Fig. 3 is a transverse vertical section through ,a plurality of stackedclosures.

Fig. 4 is a plan view, reduced, of a blank from which a closure is to beformed.

Fig. 5 is a plan View, reduced, of the blank able manner.

shown in Fig, 4 with the edge portions scored to permit ready bending toprovide a flange and to permit corrugations being formed in the flangeto take up excess material.

Fig. 6 is a plan view, reduced, of a reinforcing band adapted toencircle the mouth portion of a container; and I Fig. 7 is a plan view,reduced, of a reinforcing band adapted to be inserted interiorly of theclosure flange and secured thereto.

In the drawing 41 indicates generally a container while b denotesgenerally a closure adapted to be applied over the mouth portionthereof.

The container a includes a tapered body or wall portion I and a bottom2, the bottom 2 having 3 a depending flange 3 whereas the bottom edge ofthe body is turned upwardly as shown at 4 to engage the depending flangeof the bottom. The body or wall i, as well as the bottom 2, is formed ofpaper of the desired thickness or weight and while I have shown the bodyas being formed of a singleply it will be appreciated that it mightequally as well be formed of a multiplicity of plies such as by rollinga blank orin other suit- A reinforcing band 5 of heavy paper, cardboardor the like, is adapted to be positioned around the mouth portion of thebody and secured thereto as shown more particularly in Figs. 1 and 2 ofthe drawing. This band 5 is of such a diameter that when it is pushedupconnection is formed between the band 5 and portion 6 than would bethe case if an attempt was made to securethe band to a tapered wall. Itwill be noted particularly that the outer surface of the band 5 will beperpendicular for a purpose which will be later apparent.

The closure b, in the form of a cap is shaped or formed from a blank 0indicated more particularly in Fig. 4 of the drawing and extendinginwardly a distance from the marginal edge of this blank 0 arecircumferentially spaced scores 1 which facilitate the bending of theblank to provide a flange to be later described and to take up theexcess material caused by the forming of the flange. The closure orclosure cap includes a top portion 8 and a depending flange 9, thisflange 9 being folded from the blank c and when formed being corrugatedas shown due to the folding of the excess material. A depression I8 isformed at the juncture of the top 8 with the flange 9 and forms a seatfor the edge of a flange when a plurality of closures or caps arestacked as shown more particularly in Fig. 3 of the drawing. It will beunderstood that the seat or depression Ill extends around the outer edgeof the top and is of such a circumference as to receive the bottom edgeof the flange of a cap or closure positioned thereon in stack formationas shown more particularly in Fig. 3. When a plurality of the closuresor caps are stacked the outer walls of the flanges will be in aperpendicular line. The tops 8 of the closures or caps are formedinwardly of the flanges with circumferentially extending depressions IIwhich will allow for slight expansion of the caps or closures when beingapplied and which have a tendency to contract the caps or closures afterapplication to snugly engage the closure with the container. A ring orband [2 of paper, cardboard or similar material, is secured to the innerwall of the flange 9 and the inner surface of this ring or band isadapted to frictionally engage the outer face of the ring or bandsecured to the mouth portion of the container. It will be seen that arelatively large frictional area is provided and the closure or cap willbe held in position again accidental displacement although it mayreadily be applied or removed from the container when desired.

From the above detailed description it is thought that the constructionof both the container and closure or cap will be clearly understood aswell as the advantages thereof. In the past considerable difliculty hasbeen experienced in applyin a flanged cap or closure to a taperedcontainer but with my construction a perpendicular wall is provided atthe mouth portion of the container and it provides a relatively largearea for frictional engagement with (the closure or cap. At the sametime the mouth portion of the container is reinforced as is also thedepending flange of the closure or cap. The closures, as previouslystated, are of such a formation whereby they may be readily stacked andby supplying a circumferentially extending groove in the top 8 of theclosure or cap the diameter of the cap or closure may be slightlyincreased, or there may be a giving, so to speak, in applying theclosure or cap to the container. However, when the cap or closure isapplied the parts will tend to spring back to their normal position tosecure a close frictional engagement between the bands or rings 5 andI2.

Having fully described my invention what I claim as new and desire tosecure by Letters Patent is:-

1. A closure for a container including a top portion and a dependingflange, the top portion being formed with a circumferentially extendingflat seat at its marginal edge adapted to receive the bottom edge of aflange of a succeeding closure of a stack, the seat being of a widthcorresponding to the thickness of the flange to pre-- vent lateralmovement of one closure relative to the other.

2. A closure for a container including a top portion having an integraldepending portion, and a reinforcing band secured to the inner face ofthe depending portion and cooperating therewith to form a flange, thetop portion being depressed around its marginal edge to provide a flatseat of a width corresponding to the combined thickness of thedependingportion and associated reinforcing band and to receive thebottom edges of the formed flange of a succeeding closure of a stack toprevent lateral movement of one closure relative to the other.

3. The combination with a container including a tapered body portion anda band positioned around the mouth portion thereof, said bandcontracting the mouth portion to provide a vertical wall adapted toengage the inner surface of the band throughout its height and to form asmooth flat surface for securing the band to the container, of a closurefor the container, said closure including a top portion, a dependingflange, and a reinforcing band secured to the inner surface of theflange, the top portion being depressed around its marginal edge toprovide a flat seat of a width corresponding to the combined thicknessof the flange and reinforcing band and to receive the bottom edges ofthe flange and band of a succeed ing closure when the closures arearranged in a stack and to prevent lateral movement of one closurerelative to the other, the reinforcing band secured to the inner face ofthe flange of the closure engaging the band positioned around the mouthportion of the container when the closure is in position on thecontainen'the band of the container and band of the closure forming arelatively large frictional area for holding the closure on thecontainer against accidental displacement.
